Ricevo il messaggio di errore «Numero massimo di attivazioni superato»
You can only activate BackWPup on as many WordPress Installations as you have licences available. If you get this error message, you already activated all licences you bought. You need to delete an activation via your www-test.backwpup.com account or via your WordPress backend before you can activate again.
Troubleshooting: If you have troubles activating or deleting your licence via your WordPress backend, please check your account dashboard at www-test.backwpup.com to ensure the licence is not active in the shop on the same domain.
If you see the licence activated, delete the activation via your my account and try to activate again via your WordPress backend.
